Abstract
This paper first introduces the topology of Three-Phase PWM Voltage Source Rectifier (VSR). Then the mathematical models in three-phase static and two-phase rotary coordinate system are built. Based on that theory and the voltage-oriented vector control's idea, the paper introduces a dual-channel closed-loop control strategy with current-inner-loop and voltage-outer-loop. Active power channel is aim to make DC side voltage remain steady, and reactive power channel can regulate power factor by set current q-axis component reference. In order to prove that voltage-outer-loop is necessary, the paper builds a comparative model without a voltage loop. According to change current q-axis component reference value, illuminate reactive power channel's effect. In MATLAB/SIMULINK, the paper sets up simulation models for above cases. The simulation results show that the voltage-outer-loop is essential, and prove that current q-axis component can regulate power factor. The Three-Phase PWM Voltage Source Rectifier dual-channel double-closed-loop control strategy is effect.
